FASTENER FOR MEETING-RAILS O-F SASHES.

SPECIFICATION forming part of Letters Patent No. 374. dated NOVembeI 1837- Applioation filed April 7,1887. Serial No. 234,035. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM W. ABBOTT, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Fasteners for the Meeting-Rails of Sashes, of which the following is a specification.

The object of my improvement is to provide a fastener which cannot be operated from without, which shall draw the meeting-rails together, at the same time raising the upper sash and forcing down the lower while the sashes are being fastened, and which isreadily capable of being constructed so as to be self-lockin g.

To these ends my improvement consists in certain details of construction which will first be fully described with reference to the accompanying drawings, and then be specifically pointed out in the claims.

In said drawings, Figure I is a top view of my improved fastener applied to the meeting rails of two sashes. Fig. II is a similar view with a portion of the housing on the lower sash broken away to show the construction of the bolt. Fig. II is a top view of the bolt detached, the handle being placed in position at ninety degrees with the position shown in Fig. II. Fig. III is a view similar to Fig. II, but illustrating the method of applying a bent-wire spring in lieu of the spiral spring shown in Fig. II. Fig. IV is a' top view illustrating a construction in which the bolt is not self-1ock ing, but actuated positively in each direction. Fig. IV is a detail view of the bolt for this form of fastener. Fig.V is a vertical sectional view of the fastener shown in Fig. IV. Fig. VI is afront elevation of my improved fastener.

1 is the bolt having a handle, 2, and provided with horizontal bearing in a housing, 3,which may be screwed to the top rail of a lower sash. A metal seat, 3', is provided for the bolt 1, and thehousing 3 is appropriately chambered to receive this seat and hold it in position.

5 is a socketplate which may be fixed by screws to the bottom rail of an upper sash.

The end of boltlis provided with an eccentric or projection, 6, so that while no opposition to the entrance of the end of the bolt into the socket is made while the bolt is in the position shown in Figs. II, III, and IV, the turning of the bolt from this position to that shown in Figs. I and V will bring the eccentric or projection up against the under surface of the socket5, and so force the upper sash upward and the lower sash downward, while they are being fastened together.

A lip, 7, is made on the mouth of ihesocket to receive the bearing of the eccentric or projection 6, and thus prevent the withdrawal of the bolt; and this lip is further utilized in bringing the edges of the sashes closely together by forming the inner side of the eccentric or projection 6 with an incline or cam, 8.

An incline, 9, is provided on the inner side of the housing 3 to the left of the bolt. Along this incline the handle rides for operating the bolt, as more fully described below.

In Fig II I have shown a spiral spring, 10, surrounding the bolt, bearing at one end against the shoulder 11 on the bolt, and at the other against the shoulder 12 on the housing 3.

An inclined lip, 4, is formed on the upper surface of the socket-plate 5 immediately over the socket. Against this lip the endof the bolt 1 will strike when the sashes are being closed, and thereby the bolt is forced inward and the handle 2 allowed to drop into the position shown in Fig. II, the spring being compressed and the end of the bolt so turned that the projection or eccentric 6 will not in terfere with its entry into the socket as soon as the latter comes opposite the end of the bolt. When this occurs, the spring 10 being released forces the bolt into the socket, and the handle 2, riding on the incline 9, turns the bolt, so as to automatically lock it in position. The handle may then be turned over by hand to the position shown in Fig. I, to force one rail down and the other up and draw the rails firmly together.

In Fig. III a bent-wire spring, 13, is fixed at one end to the housing, and bears behind a shoulder on the bolt 1. The operation of this fastener is, however, the same as that shown in Fig. II. In Fig. IV, however, I have shown the invention applied to a fastener which is not self-locking. In this a projection, 14, preferably cam-shaped, is formed on the bolt 1 to bear behind an inclined shoulder, 15, (shown in Fig. V, and in dotted lines in Fig. IV.) It will be seen that the inclines 14 15 force the bolt into the socket as the handle is turned to the position shown in Fig. I, while the incline 9, bearing on the handle, forces the bolt out of the socket when the handle is turned to the position shown in Fig. IV. In this form the projection 14 prevents the withdrawal of the bolt, but in the other forms shown the eccentric or projection 6 is made of such size as to abut against a shoulder, 16, on the housing, and so prevent the withdrawal of the bolt.

The simplicity of my improved fastener, the case with which the main parts are cast with out theneccssityof being subsequent]ydressed, the dispensing with drilling and rivets, and the perfection with which it is retained in locked position are the main points in this improvement comparing favorably with prior constructions.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. In a fastener for the meeting-rails of sashes, the combination of a housing adapted to be fixed to the lower sash, and bearing on its inner side a part or projection, 9, having a rapidly-inclined upper surface, a bolt having bearing in said housing, a handle on the inner end of said bolt, adapted to bear on the inclined surface of said part or projection of the housing, a cam or projection,6, at the other end of the bolt,-having its inner face inclined so as to guide the bolt in the same direction as does the inclination on the inner side of the housing, means for forcing said bolt outward when turned, and a socket-plate adapted to be fixed to the upper sash having inturned lip 7, the whole being constructed and arranged substantially as and for the purpose set forth.

2. The combination of a housing adapted to be fixed to the lower sash, and having an incline on its inner side, a bolt having bearing in said housing, a handle on the inner end of said bolt, adapted to bear on said incline, a cam or projection on the outer end of said bolt, having its inner face inclined so as to guide the bolt in the same direction as does the inclination on the inner side of the housing, a spring carried by the housing and adapted to force said bolt outward, and a socket-plate adapted to be fixed to the upper sash having outwardly-inclined lip above its socket and an inturned lip at the mouth of the socket, the whole being constructed and arranged substantially as and for the purpose set forth.
